Adenovirus DNA, Quantitative Real-Time PCR – Accurate Detection & Viral Load Monitoring

The Adenovirus DNA, Quantitative Real-Time PCR Test from Lab Tests Dubai is a highly sensitive molecular diagnostic tool that detects and quantifies adenovirus DNA in stool samples—a key method for diagnosing adenoviral gastroenteritis and monitoring viral load in high-risk patients.

Adenoviruses (especially serotypes 40 and 41) are common causes of gastrointestinal infections in children, while other serotypes can cause respiratory, ocular, or systemic disease—particularly in immunocompromised individuals.

This test is essential for:

• Diagnosing persistent diarrhea in infants and young children
• Monitoring adenovirus load in transplant recipients or immunocompromised patients
• Evaluating fever of unknown origin with GI symptoms
• Detecting viral shedding in outbreak settings (e.g., daycare centers)

Using quantitative real-time PCR technology, this advanced test not only confirms the presence of adenovirus but also measures viral load (copies/mL)—enabling clinicians to:

• Assess infection severity
• Monitor response to therapy
• Guide infection control measures

Available with home sample collection and sterile kit delivery, Lab Tests Dubai ensures accurate, private, and stress-free testing—so you can get answers fast, especially when every day counts.

Why You Need This Test

If you or your child has prolonged diarrhea, fever, or is immunocompromised, this test could reveal a potentially serious viral infection.

You need the Adenovirus DNA PCR Test if:

• Your child has watery diarrhea lasting >5 days
• You’re an organ or stem cell transplant recipient with GI symptoms
• You’re on chemotherapy or immunosuppressants and feel unwell
• You have fever, abdominal pain, or vomiting without bacterial cause
• You’re being evaluated for viral gastroenteritis or sepsis-like illness
• You work in or your child attends a daycare with a virus outbreak

This test helps:

• Confirm adenoviral infection when cultures or antigen tests fail
• Monitor viral load in immunocompromised patients
• Guide antiviral decisions (e.g., cidofovir in severe cases)
• Prevent complications like dehydration or systemic spread

Early detection = faster recovery and better outcomes.

Symptoms That Indicate This Test

Consider the Adenovirus DNA Test if you or your child experience:

✅ For Gastrointestinal Infection:

• Watery diarrhea (not bloody)
• Fever and abdominal cramps
• Nausea, vomiting, loss of appetite
• Dehydration signs (dry mouth, reduced urine)

✅ For High-Risk Patients:

• Post-transplant fever or diarrhea
• Unexplained cytopenia or hepatitis
• Respiratory symptoms with GI involvement

✅ For Children:

• Diarrhea lasting more than 5–7 days
• Recurrent or severe gastroenteritis
• Failure to thrive due to chronic infection

These signs may point to adenoviral gastroenteritis—and this test provides definitive molecular confirmation.

Natural Production: How Adenovirus Spreads and Replicates

Adenoviruses are non-enveloped DNA viruses that infect humans through:

• Fecal-oral route (contaminated water, food, surfaces)
• Respiratory droplets
• Direct contact

Once ingested, the virus replicates in intestinal epithelial cells, causing cell damage and inflammation—leading to diarrhea and shedding in stool.

In immunocompromised individuals, adenovirus can:

• Spread to liver (hepatitis), bladder (hemorrhagic cystitis), lungs (pneumonia), or CNS (encephalitis)
• Cause life-threatening systemic infection

Why Quantitative PCR Matters:

• Detects low levels of virus missed by antigen tests
• Measures viral load—critical for monitoring transplant patients
• Identifies serotypes (some more virulent than others)

This test is not for routine diarrhea—but vital for severe, persistent, or high-risk cases.

What Happens If Untreated? Risks of Ignoring Adenovirus Infection

Ignoring adenovirus in vulnerable patients can lead to:

⚠️ Severe Dehydration & Malnutrition – especially in infants
⚠️ Systemic Infection – hepatitis, pneumonitis, encephalitis
⚠️ Graft Dysfunction or Loss – in transplant recipients
⚠️ Hemorrhagic Cystitis – painful, bloody urination
⚠️ Chronic Viral Shedding – risk of transmission

The good news? Most cases are self-limiting in healthy individuals, but:

• Immunocompromised patients may need antivirals (e.g., cidofovir)
• Supportive care (hydration, electrolytes) is crucial
• Isolation and hygiene prevent outbreaks

Early testing = prevention of life-threatening complications.

How to Prepare for the Test

To ensure accurate results:

✅ No fasting required
✅ Collect stool sample in sterile container (provided by Lab Tests Dubai)
✅ Avoid antibiotics or antivirals unless medically necessary
✅ Inform your doctor of:

• Transplant or immunosuppression status
• Recent infections or hospitalizations
• Current symptoms and duration

A fresh stool sample is required—collected at home or clinic and transported under cold chain.

Test Overview: Quantitative Real-Time PCR Method

Report Includes:

• Detected / Not Detected status
• Viral Load (copies/mL) – if positive
• Interpretation notes for clinicians

Note: For respiratory or systemic adenovirus, blood, urine, or respiratory samples may be tested separately.
